I encountered a range of dependency problems, when I tried to run this in an alpine docker container. I wanted to share how to make this run with (elixir) puppeteer-pdf=1.0.3 and (node) puppeteer-pdf=1.2.0. The main source of making this work was the documentation on the official Puppeteer GitHub page.

Prepare your alpine Docker container

I used this Dockerfile for building the container:

RUN apk add --update 
RUN apk update && apk upgrade && \
    echo @edge http://nl.alpinelinux.org/alpine/edge/community >> /etc/apk/repositories && \
    echo @edge http://nl.alpinelinux.org/alpine/edge/main >> /etc/apk/repositories && \
    apk add --no-cache \
    nodejs \
    nodejs-npm \
    inotify-tools \
    chromium@edge=~73.0.3683.103 \
    nss@edge \
    freetype@edge \
    freetype-dev@edge \
    harfbuzz@edge \
    ttf-freefont@edge

ENV PUPPETEER_SKIP_CHROMIUM_DOWNLOAD true
RUN npm install puppeteer-pdf@1.2.0 puppeteer@1.12.2 -g

COPY assets/config/puppeteer-pdf.js /usr/lib/node_modules/puppeteer-pdf

Set launch arguments in puppeteer-pdf.js

Change the following line in your /usr/lib/node_modules/puppeteer-pdf/puppeteer-pdf.js file:

# Before
const browser = await puppeteer.launch({args: ["--no-sandbox"] });

# After
const browser = await puppeteer.launch({executablePath: '/usr/bin/chromium-browser', args: ["--no-sandbox", "--disable-software-rasterizer", "--headless", "--disable-gpu", "--disable-dev-shm-usage"] });

Now, you "should" be able to use the (elixir) puppeteer-pdf library on alpine as well!

Problems encountered

Just for documentation purposes, I'm adding some error logs that I've encountered until I found this solution.

Without settting the --disable-gpu and --disable-software-rasterizer flag

Failed to load /usr/lib/chromium/swiftshader/libGLESv2.so: Error loading shared library /usr/lib/chromium/swiftshader/libGLESv2.so: No such file or directory

Bonus: Insert your own .css file.

In your puppeteer-pdf.js file, add the following line:

...  
# Add the following line:
await page.addStyleTag({path: '/src/priv/static/css/app.css'}); // <--- Add this line
await page.pdf(options);

await browser.close();
...
